Methods, systems, and apparatuses are disclosed for server selected bitrate streaming. A server receives a request from a user device for data segments at a first bitrate. The server determines a second bitrate for transmission of the data segments to the user device. The server transmits the requested data segments at the determined second bitrate.

Server selected variable bitrate streaming

The disclosure relates generally to providing content from a source to a user device. In one implementation, a source such as a server receives a request for a master manifest file. The server may identify one or more other manifest files and at least one data block associated with the content. The other manifest files can include manifest files referenced by the master manifest file, or can include manifest files associated with related content. The requested master manifest, the one or more other manifest files, and the at least one data block can be pushed to the user device.

Methods and systems for content delivery using server push

Systems and methods are described for retrieval and output of content in a way that addresses concerns with storing multiple copies or versions of a piece of content. The piece of content may have associated computer instructions that allow the client to access alternate portions of the piece of content during consumption. This allows the content provider to store a single copy of the complete piece of content while enabling consumers to access alternate audio or video portions of the content. A new playback architecture may execute instructions associated with a piece of content. Instructions associated with a piece of content may directly affect consumption by the consumer client and may be dependent upon user preferences or interests.

Content playback control

Systems, apparatuses, and methods are described for protecting the integrity of a playlist, and/or for determining whether a playlist has been altered. The playlist may comprise references to segments of multiple content types. The references may be obfuscated, and/or confirmation data may be used to detect playlist alteration.
